BMP180 is a high-precision, small size, ultra-low power pressure sensor that can be used in mobile devices.

Pressure range: 300 ~ 1100hPa (9000 meters above sea level ~ -500 meters); Low power consumption: 5μA in standard mode.

Using a sensor as capable as the BMP180 you can achieve accuracy of 1m, with noise of only 17cm in ultra high resolution noise. The device will operate at only 0.3uA meaning low current draw for battery powered applications.

Support MP3 format, playing power on automatically.When mp3 is played the red LED flashes.

Support U disk (test 32G), TF Card (test 16G) play mode; power on default TF card mode, if the TF card does not exist automatically jump to the U disk mode,and both devices have installed,then you can manually set the play mode.For details please see the key operating instructions

Buttons can be adjusted up and down to control songs,volume up and down, pause or play, mode switching.For details please see the key operating instructions.

Using AD620 as the main amplifier, can amplify uV, mV voltage. Magnification 1.5-10000 magnification, adjustable. High precision, low offset, better linearity. Adjustable zero to improve accuracy. (The use of the module requires a certain electronic foundation. If there is no basic customer, please buy with caution)

Amplification the potentiometer is used to amplify the input signal, and the amplification is up to 1000 times, only need to pass a potentiometer to adjust.

Adjustable zero point adjust the zero point through the zero-adjusting potentiometer to improve the accuracy. The phenomenon of zero drift appears to meet customer needs.
